Numbers higher than $3FFFFFFF don't work correctly

[radekh]

Try following

n=$3FFFFFFF
print n

n=n+1
print n

I've reproduced this on the emulator. The docs say integers are about +/- 2 billion, i.e. 7fff ffff, so this should be well within range.

Interestingly this is a VERY similar result to the one I got in #50:

I used the FoenixIDE to investigate this bug. I set n to $7FFFFFFF then stopped the IDE. Examining memory I see the variable is set to the correct value. The problem would appear to be within the code that prints a variable. Possibly one of the most significant bits is used to indicate whether a number is fixed or floating point. Some more digging in to the SB code is needed.
